Fabrication and Heat Treatment of Super Alloy Hastelloy N
Machinability
Hastelloy® N can be machined using conventional machining methods which are used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-based coolants. Heavy lubricants are used for, tapping, drilling, boring, or broaching.
Forming
Hastelloy® N is formed using conventional techniques.
Welding
Hastelloy® N is welded using gas-tungsten arc welding, gas metal-arc welding, shielded metal-arc welding. Submerged-arc welding method is not preferred.
Heat Treatment
Hastelloy® N does not respond to heat treatment.
Cold Working
Hastelloy® N can be cold worked using standard tooling. Soft die materials such as zinc alloys, and bronze are used for producing good finish and reducing galling problems. During the sequence of cold forming process, intermediate annealing can be performed.
Annealing
Hastelloy® N is annealed at 1177°C (2150°F) followed by cooling.
Hardening
Hastelloy® N is hardened only by cold working.
